Thank you for all of the replies and suggestions. I am relieved to realise that at least I was not missing anything obvious regarding accessing the heads of the grubscrews. I shall presevere, having finally managed to drill out the remains of the old, heavily worn grub screws which had been brazed in by a previous owner.
Regards,
Jamie.
